Permissible liability provisions in policy.

(A)
Any policy which grants the coverage
required for a motor-vehicle liability policy may also grant any lawful

motor-vehicle liability policy and such excess or additional coverage shall not
be subject to sections
4509.01 to
4509.78, inclusive, of the Revised

the term "motor-vehicle liability policy" shall apply only to that part of the
coverage which is required by such sections.

Any motor-vehicle liability policy may
provide that the insured shall reimburse the insurance carrier for any payment
the insurance carrier would not have been obligated to make under the terms of
the policy except for such sections.

(C)
Any motor-vehicle liability policy may
provide for the prorating of the insurance thereunder with other valid and
collectible insurance.
